The evolution of cosmic string loops in Kerr-de Sitter spacetimes
Zhengyan Gu, Hongbo Cheng
The equation of cosmic string loops in Kerr-de Sitter spacetimes is derived. Having solved the equation numerically, we find that the loops can expand and exist except for too smal…

The special nontopological scalar solitons in anti de Sitter spacetimes
Hongbo Cheng, Zhengyan Gu
In this letter the nontopological scalar solitons are investigated in an anti de Sitter spacetime. We find analytically that the solitons obeying the necessary conditions $m=\frac{…

The nontopological scalar solitons in de Sitter spacetimes
Hongbo Cheng, Zhengyan Gu
In this letter the nontopological scalar solitons with a self-interaction potential are investigated in a static de Sitter spacetime and their field equations are derived. In parti…
